Specification of Letters Patent.

Patented June 11, 1907.

Application filed January 9, 1906. Serial No. 295,234.

proven'ients in Grates, of which the following is a specification.

This invention relates to a grate for stoves or furnaces provided with improved means for igniting the coal or other fuel by a preliminary charge of gas.

I n the accompanying drawing: Figure 1 is a plan of my improved grate; Fig. 2 a side View thereof; Fig. 3 a longitudinal section on line 33, Fig. 1, and Fig. 4 a cross section on line 4-4, 'Fig. 1. I

The grate is composed of a series of spaced longitudinal bars a, a, united at the front and rear by the cross bars o a, the whole forming an integral casting. The bars a, are [latter or thinner than the bars a with which they alternate the bars a, extending below the bars a. Below each bar a, there is secured a trough shaped gas duct b, which abuts at its front and rear ends against the cross bars a a, respectively. The trougl'i has upper notched or corrugated edges which in conjunction with the lower side of bar a, form lateral discharge orifices 1), opening into the spaces a", between bars a, a. Means are provided for removably securing the troughs to the bars, so that, when the grate is burnt out, the troughs may be removed and re-fitted to a new grate. These means are shown to consist of screws 0, passing through the troughs and tapped into bars a.

The grate has the front gudgeona", and the rear gudgeon a". is hollow as at a and adapted to be coupled to a gas pipe. The inllowing gas is mixed in the gudgcon with air entering through a lower perforation (L7, and thence [lows into the front cross bar (15, which is hollow. From this bar the gas enters, through ducts (1.", the troughs i), from which it escapes tl'irough the orifices I). Here the gas is ignited, the flame reaching the iuel supported upon the grate, by

means of the spaces a". As soon as the "fuel is sutl'iciently kindled, the gas is turned off.

\Vhat I claim is:

A grate provided with a series ol spaced longitudinal bars, a front cross bar formed hollow throughout the greater portion of its length, a rear cross bar, a hollow gudgeon communicating with the front cross bar and provided with an opening in its bottom for communication with the atmosphere and with the interior of the gudgeon, the said hollow cross bar having a series of openings therein, gas ducts extending along alternate longitudinal bars and communicating with the aforesaid openings of the hollow cross bar, the upper edges of the ducts being notched to provide gas outlets, and means for ren'iovably securing the ducts to the integral casting.
